42 Fun Facts For People Who Love To Learn

42. How Convenient!

The device you’re reading this on probably has a QWERTY keyboard. Many different arrangements were used by early typewriters, but QWERTY is the one that ended up sticking.

Strangely, one of the longest words that can be typed on a single row of a QWERTY keyboard is “typewriter.”

41. A Big Heart

The blue whale is the largest animal that’s ever existed—and it's not even really close. A full-grown Blue weighs almost twice as much as the heaviest dinosaur.

An animal that big needs a serious heart to keep it going: The blue whale’s heart can be the size of a small car, weigh 1,300 pounds, and has vessels so large that a human could swim in them... although I imagine a Blue Whale would not be thrilled about that experiment.

40. Tennis Anyone?

Your lungs are filled with tiny sacs called alveoli that draw oxygen from the air you breathe into your bloodstream. In total, the average adult has around 600 million of these alveoli, and their combined surface area is roughly the size of a tennis court.

39. Take Flight

Aviophobia, or the fear of flying, affects millions of people.

But not only are plane crashes incredibly rare, they aren't even always fatal. In fact, between 1983 and 2000, 96% of people who were involved in plane crashes actually survived! It really is the safest way to travel.

38. Bit by Bitcoin

Satoshi Nakamoto is the inventor of bitcoin.

Nakamoto published a paper in 2008 that first described the currency, and released the first version of a bitcoin software client in 2009. But “Satoshi Nakamoto” is a pseudonym, and to this day no one knows who he or she is. The last anyone has heard from them was in 2011, and various sleuths have tried to uncover their identity (unsuccessfully) ever since.

37. Take the Stairs

The entire state of Wyoming has only two escalators, both in the city of Casper. They’re so rare that some Wyoming residents visit these escalators just for the novelty of it, with one of them describing it as “like riding a tilt-a-whirl, but only slower.”

Annnnd that it is the most adorably mid-Western statement ever made. No wonder we love the middle states.

36. Christmas in Vietnam

If you were listening to the radio in Vietnam in April, 1975, you might have heard a surprising song: Bing Crosby’s “White Christmas.” That’s because it was the secret signal for Americans to evacuate the country in an event called Operation Frequent Wind.

Speaking of White Christmas, here's another fun fact: Bing Crosby's ode to the holiday is actually the best-selling single of all time. It's true!

35. Half a Million on Your Head

​The F-35 fighter jet is one of the most expensive military projects of all time. It’s estimated that by the time the project is finished, it will have cost $1.4 trillion. Clearly, no expense was spared at any point, and that includes in the pilot’s helmets: Each F-35 helmet costs a whopping $400,000.

34. Hope You Like Walking

In an effort to make the city more pedestrian-friendly and to lower its carbon footprint, the city of Oslo in Norway made plans to ban all cars from entering the city center by 2019. And believe it or not: It worked! In 2019 Oslo reported exactly 0 pedestrian or cyclist fatalities.

33. A Cat by Any Other Name

​The cougar goes by more names than any other animal. You might know it as a puma, mountain lion, panther, catamount, or one of another 40 English, 18 native South American, and 25 native North American names.

32. Dinner and a Show

The founder of the iconic Japanese restaurant chain Benihana was a man by the name of Rocky Aoki.

If you recognize that name, it’s because his son is DJ Steve Aoki and his daughter is actress/model Devon Aoki. But although Rocky was a millionaire, he didn’t spread the wealth to his children. Since he came from nothing, he wanted his children to do the same, so never gave Steve any money to start up his record label.

31. Searching for Giants

The Lewis and Clark expedition is famous for many reasons, but they had one goal you might not expect: Thomas Jefferson asked them to find a mammoth.

Turns out, Jefferson had a thing for mammoths (or, more accurately, American Mastodons). He was completely enamored with the extinct behemoths, and held out hope that they continued to live many miles away in the west of America. So when he sent Lewis and Clark out on their famous expedition, he told them to look for mammoths. What a discovery that would have been!

30. It’s-a-Me! Tom Hanks!

Tom Hanks was initially cast to play Mario in the 1993 movie Super Mario Bros. However, this was early in Hanks’ career, and the studio heads were concerned about his star power (no pun intended) and how much money he was asking for. The studio then replaced Hanks with Bob Hoskins, who they considered to be the more bankable star. The movie? Did not make bank.

Shoulda cast Chris Pratt...

29. Shhhh!

The British Library has more than 150 million items, and that number keeps growing. Every year, more than 3 million items are added to the collection, meaning that 12km of shelves need to be added yearly to accommodate it all.

28. Smells Like…Deodorant!

When he set out to write “Smells Like Teen Spirit,” Kurt Cobain said that he was trying to write the ultimate pop song in the style of the Pixies.

He came up with the title when a friend of his (Kathleen Hanna, the lead singer of Bikini Kill) wrote the phrase “Kurt Smells Like Teen Spirit” on his wall. Cobain thought the sentence had a certain poetic ring to it, and the rest is history. Really though, Hanna just meant he smelled like Teen Spirit, a popular deodorant at the time.

27. Dinosaurs Didn't Go Extinct

Who doesn't wish that the dinosaurs were still alive for us to see today? Well, good news—they didn't go extinct, and they're all around us! That's because one kind of dinosaur survived their extinction: Birds! Birds didn't just evolve from dinosaurs, they are dinosaurs, just very specialized ones.

26. Throwing Around The PigCowskin

Despite the common nickname, NFL footballs are actually made from cow leather, and it takes 3,000 cows to supply the league with footballs for just one season.

25. Space Pharaohs

The era of Ancient Egypt lasted for thousands of years, which can be hard to wrap your head around. To put it in perspective, the Great Pyramid of Giza was built roughly between 2550 and 2490 BC, while Cleopatra took the throne in 51 BC. That means that the Cleopatra’s reign was closer in time to the moon landing than it was to the building of the Great Pyramid.

24. The Shrimp from Hell

The mantis shrimp attacks its prey by essentially punching them extremely hard. Their fist-like appendages can punch so fast that they can boil the water around them and split your finger to the bone.

23. How Do You Sing Along?

Spain’s national anthem has no words. It’s called the "Marcha Real" and it’s one of four anthems on earth that’s entirely instrumental (the other countries are Bosnia and Herzegovina, Kosovo, and San Marino).

22. No Expiry Date

Everyone’s had to deal with emptying a fridge of food that’s long since gone bad, but there’s one food that you don’t have to worry about: honey. Because of its unique makeup, it never spoils, and people have found pots of honey that are thousands of years old with the sweet stuff still perfectly preserved inside.

21. Watching the Universe

​The static on your old TV set is actually caused in part by the Big Bang. Television static is caused by your antenna picking up radiation in the atmosphere. Some of that radiation is the “cosmic microwave background,” which is leftover radiation from the formation of the universe. So the next time you see static on a TV, know that you’re looking actually looking at part of the beginnings of our universe.

20. Checkmate

It’s common knowledge that chess is a complicated game, but just how complicated is hard to imagine. In fact, there are so many different possible moves in a chess game that it isn’t even worth the impossible amount of effort it would take to calculate it. But scientists can confidently say that there are far more potential unique chess games than there are atoms in the entire universe.

19. We Learn Fast

Before 1903, no human had ever achieved powered flight. But once we passed that barrier, progress started happening fast. Airplanes were used in warfare within a decade, and people had landed on the moon just 66 years after the first flight. Not bad considering people had been trying to fly for millennia.

18. Months of Traffic

Next time you’re stuck at a red light, try not to do the math of how much time you spend there—it won’t make you feel any better. Drivers spend an average of two days a year waiting at red lights, which adds up to about 4 months over the course of a lifetime driving if you live to be 75.

17. Smart Birdy

​Along with dolphins and chimpanzees, the Eurasian magpie is right up there with the most intelligent animals on Earth. The mirror test (the ability to recognize yourself in a mirror) is seen as an important test in animal intelligence, and the Eurasian magpie is the only non-mammal that has passed it. It also has one of the largest brain-to-weight ratios in the animal kingdom and has been observed using tools, working in teams, playing games, and grieving.

16. More Unique Than Unique

Inhabitants of Fort Keogh in Montana found snowflakes that were more than a foot across during a snowstorm in 1887. Some of the flakes were 15 inches wide, the biggest ever recorded.

15. Wealth Gap

If you combined the wealth of the 48 poorest nations on earth, they would still have less money than the world’s three richest people.

You're right: I suppose that's not really a "fun fact". But we did promise mind-blowing trivia as well... and that is certainly astonishing.

14. I Wonder if They Tried Honking

The biggest traffic jam of all time happened in 2010 in China. Mostly taking place on China National Highway 110, it affected cars for over 60 miles. The jam lasted for more than 10 days, and some people were trapped in their cars for five days straight.

13. I Bet, I Bet, 50 Words or Less

Green Eggs and Ham is one of the most popular children’s books of all time, and if you count them up, it uses exactly 50 different words. That’s because Dr. Seuss wrote it on a bet: his publisher bet Seuss $50 that he couldn’t write an entire book with 50 or fewer words.

12. Duck Money

Scrooge McDuck was named by Forbes as the richest fictional character in the world. They estimate his personal net worth to be $65.4 billion. They said he made his money in mining and treasure hunting, and that he kept most of his wealth, of course, in his gold coin swimming pool.

11. Pennyweight

The smallest birds on earth are hummingbirds. Although they come in a variety of sizes, the smallest weighs as little as 2.4 grams. For comparison, a US penny weighs 2.5 grams.

10. #onelongbook

If you took everything posted on Twitter every day and put it into a book, that book would be 10 million pages long.

9. Fluffy and Heavy

​Clouds are made up of water vapor that’s collected in the atmosphere. Because they float in the sky, you might think that they’re light as a feather, but the average weight of a cumulus cloud (the really fluffy-looking ones) is actually 1.1 million pounds.

8. Get Your Peafowl Straight

Peacocks are all male. They’re actually a kind of bird called a peafowl, and the females are called peahens.

7. These Colors Do Fade

Red, white, and blue no more. In 2012, NASA confirmed that five of the six American flags planted on the moon by various lunar missions were still standing where they were. The catch? The flags don’t really look like American flags anymore. In the harsh radiation of space and the bright sunlight on the moon, unfiltered by any atmosphere, the flags have been bleached completely white.​

6. Don't Mess with the IRS

Al Capone was one of America's most famous mob bosses, ruling the Chicago underworld and making an estimated $100 million per year.

So what brings down a gang lord like that?

Turns out that Capone's crimes only caught up with him because the IRS looked into his tax situation. He'd gone years without filing, and in the end, that's the crime that did him in. He was given an eleven-year sentence for tax evasion, the longest tax evasion sentence ever given in the United States.

5. The Big Guys Can’t Jump

Elephants, rhinos, and hippos are some of the very few types of mammal that can’t jump.

While rhinos and hippos will occasionally get all four feet off of the ground while running, the elephant never does at all, staying firmly landlocked at all times.

Remember that next time you're trying to have fun with an elephant: if you break out a skipping rope, you're really going to hurt their feelings.

4. Try to Name Them All!

English is a complicated language, and words like “set” and “run” don’t make it any easier. For years, set was considered to have the most meanings of any word, with the Oxford English Dictionary giving it 430 separate definitions in 1989. But according to OED's chief editor John Simpson, the word “run” has surpassed it with a whopping 645 meanings as of 2011!

3. Better Loot

Confederate cavalry commander James Ewell Brown “J.E.B.” Stuart once sent a telegram to Union General Montgomery C. Meigs complaining about the quality of the mules he had just stolen from Union soldiers. “Gen. Meigs,” he wrote, “will in the future please furnish better mules; those you have furnished recently are very inferior.”

2. A Fact About "Having Fun"

Skyn Condoms performed surveys to find out the sex habits of U.S. millennials by State. They learned that a surprising number of people from California, for example, had sex in a school. According to their findings:

• Millennials from Georgia were most likely to pleasure themselves multiple times per day.
• More than half of the population of sexually active millennials from Kansas have done it in a hot tub or pool.
• Millennials in Massachusetts were most likely to have had a one-night stand.
• Millennials in New York were most likely to have a threesome.

1. Poopy Time

Not such a fun fact: Toilet paper is so ineffective that using it to wipe your butt after you poop doesn't even prevent health problems such as urinary tract infections. It simply doesn't remove all the poop. There's also research to suggest aggressive wiping with toilet paper can cause anal fissures and even hemorrhoids. Doctors recommend using wet wipes instead, which are far more effective at removing fecal matter.
